Organisms in the environment

2.1 Photosynthesis

Carbon Dioxide + Water --> Glucose + Oxygen

During photosynthesis light energy is transferred to chemical energy.

Leaves are well adapted for photosynthesis.

1. The sun.

2.2 Limiting Factors

Plants grow best when they have enough light, carbon dioxide and water, and are kept at a suitable temperature.

If any of these conditions are not met, the rate of photosynthesis will be limited.

1. If the temperature is too cold and cannot work effectively. 

2. The variable in which you meassure.  Usually on the y axis.

2.3 How Plants Use Glucose

Plants and algal cells produce glucose during photosynthesis.

Glucose produced in photosynthesis can be used in a variety of ways.

Plants and algae also need nitrate ions to make proteins.

1. fats, oils, insoluble starch

2.4 Making The Most Of Photosynthesis

Temperature, light levels and carbon dioxide levels affect the rate of photosynthesis.

Plant growers can artificially control the environment to improve plant growth.

1. Temperature, carbon dioxide and light levels.
